My invention" relates to a power operatedgrain deflector, and isparticularly applicable foruse with a grain car unloader of the type inwhich a side door grain car is tilted both laterally and'longitudinallyin order to deliver through the side door the grain con tained withinthe car. One object of my invention is to provide a grain deflectorwhich may be inserted through the side door into the car duringthetilting operation, in order to deflect from the car grain which wouldotherwise not escape through the door. An-

other object is the provision of such a deflec- V tor as maybe poweroperated and controlled with a minimum of'labor' and supervision.

Another object is the provision of such a d-eflector which will occupy aminimum of space when out ofuse, and which, for example, may

I be folded along the side of-the'car and its supporting cradle, whenwithdrawnfrom the car. Another objectis the provi'sloniof such adeflector as williautomatically fold into horizontal alignment with thecar, whenv it is withdrawnfrom the car; Another object is the provisionof means for withdrawing said deflector initially along the plane of thecar bottom, during the beginning of its withdrawal, and for lifting itupwardly away from the bottom of the car after a predetermmed portion ofitsexcursionof withdrawal has been completed. Another object is theprovision of a system of weights and counterweights which is operated,in association'with actuating motor means, for eiiecting the lift.- ingof the deflector'at'a predetermined point in its movement Another objectis the provision of improved guiding means for such a deflector, duringits insertion into and its withdrawal from the car fOther objects willappear from time to time in the course ofthe specificationland claims.

Considering first the general showing of I illustrate more or lessdiagrammaticallya car unloader' structure, the details of which do notof themselves form part of the present invention, but must be to someextent shown in order to illustrate the application of the presentinvention. A car support or cradle, generally indicated as A, isprovided with the arcuate tilting support A resting, for example, uponrollersA A indicates-a cable anchored at either end, as atv A to theopposite ends of the arcuate member A The cable A passes aboutfanysuitable drum A which maybe driven through the gear reduction A by anysuitable motor means A l s It will be understood that through theactuation of themotor A? the car support may be Figure 11 is a sectionon the line 11-; '1 1f0 V support A, means are provided for tilting ittransversely. I illustrate, for example, a downward extension C with thegear segment in mesh with the pinion G which may be driven through thegear C and the pinion C and any suitable power, for example a motor C-It will be seen that the transverse tipping excursions is through asubstantially smaller arc than the endwise tipping excursion; an arc of15 degrees is ordinarily sufficient. It will be understood, of course,that the support A, with the depending portion C, is tilted laterally inrelation to the cradle as a whole, and in particular is tilted laterallyin relation to the arcuate members A In operation the lateral tiltingtakes place first and then, the supporting structure as a whole islongitudinally tilted.

Grain doors are ordinarily provided with wooden inner doors within thenormally sliding doors of the car. These inner doors may merely beboards nailed in the car from within, or unitary board structures. Inany case they may be removed by an outward pressure against them, afterthe permanent sliding door of thegrain car has been moved out ofalignment with the car door. I illustrate, as a means for removing thesedoors, a structure which may be moved into contact with the inner doorwhen thecar is in the upright position in which it is shown in Fig. 2.The lateral tilting of the car moves the car against this fixed meansand gets the result of thrusting the grain door inwardly against thegrain, although it is the part which'is moved while the door remainsstationary. I illustrate as means for effecting this result the doormoving member D, which is mounted upon an arm or supporting structure Dwhich may be positioned in proper position in relation to any given carand door, as by the connecting arm D which may be set by means of asegment D with its ratchet teeth D which may be held as by the pawl D toprevent retrograde movement of the segment. The segment may be movedforwardly, as through the bevel gear D the pinion D and the manuallyoperable handle D The details of this car-opening mechanism form no partof the present invention and are herein summarily indicated anddescribed merely to make clear the whole operation of removing the grainfrom the car. It will be understood that when the member D is placed inproper position against the grain door, the car is tilted laterally, asby rotation of the gear C When the car has been tilted laterally and thedoor removed, the grain will pour out into any suitable receivinghoppers or means not herein shown, being received first upon anysuitablechute or incline D Any suitable means may be employed, forexample thecable D passing about the sheaves D, for lifting the door removingmember D out of the line of flow of the grain and out of the path ofmovement of the deflector. The final position of the member D isillustrated, for example, in Fig. 9, with the car tilted and the graindoor D, upon the member D, positioned upwardly out of line with thedeflector member.

Assuming that the car has been transversely tilted and the door has beenremoved in the position in which it is shown in Fig. 9, and that the carsupport as a wholerhas been longitudinally tilted one or more times, tocause the escape of asubstantial proportion of the grain, then thedeflector structure is employed, the deflector proper being thrusttransversely across the car floor, at an angle, to deflect outwardlythrough the car door opening the remaining grain, as the car is againlongitudinally tilted. This provides a means for disposing of the grainwhich collects in the corner of the car, and which would not normallyescape from the car in response to the ordinary tilting operation abovedescribed.

The deflecting structure is generally shown in Fig. 3, wherein isillustrated the deflector blade E, which is shown as higher at its inner than at its outer end. It is overhung along its upper edge as at Eand may be provided along its lower edge with any suitable bottom memberE of belting or the like, which serves to protect both the deflectormember itself and the bottom of the car from battering, and which tendsto make easier the sliding of the deflector across the bottom of thecar. It also tends, through its flexibility, to make a tighter, cleanerconnection with the floor.

G generally indicates the deflector-actuating arm secured at one end otthe vertical shaft K and held against rotation in relation thereto. Thearm, which is shown in section in Fig. 8, may be formed of the channelmembers G connected by side plates G Pivoted to the arm at its oppositeend, as at G", is the guiding or lifting block G on which are mountedthe three sheaves 'GG. Pivoted in turn to the block G, as at G forrotation about a generally horizontal axis, is the guiding andsupporting arm generally indicated as G The arm is pivoted at itsopposite end, as at G", to the deflector member E. The arm G as shown insection in Fig. 10, may be formed of two angle members G G, in positionon opposite sides of the deflector member E andspaced therefrom by anysuitable spacers G. In order to permit rotation of the member E aboutthe pivot G", it is pro vided with an arcuate slot G in line with whichare the spacers Gr through which pass the bolts G which tie thestructure together. G is a plate which is proportioned to mask thearcuate aperture G, to prevent the escape of grain therethrough. Theplate is fixed in relation to the arm but is so proportioned as to coverthe aperture G when the deflector member is in operative position. Therotation of the arm G in relation to the block G is limited, for examplebythe upper and lower stops G Rotation of the deflector E in relation tothe arm G is limited, in the first place, by the relation of the blocksG to the arcuate slot'G and in the second place by the stop G upon'thedeflector E, which engages the lower side of the member G when thedeflector is lifted free from the floor, in response to the tilting ofthe deflector about the pivot G", by gravity;

H generally indicatesv a connecting link which is providedwith anadjustmenaas at H .It is pivoted at one end, as at H to the block G Atthe other end it is pivoted, as at H to the sliding shoe H*, which ismounted to slide longitudinally along the arm G. This structure is shownin section, for example, in Fig. 8. The shoe H may be guided,

for'example by the lower, outer angle membersH andthe upper, inner anglemembers H. The inwardly turned flanges of these angles form a trackbeneath the arm G, along which track the shoe H may slide as the arm Grotates. Referring to Figure 7 the sliding shoe H is indicated in dottedline and, in the position in which the parts are there extends from theright of'the camroller H to the left of the cam roller H On the lowersideof the shoe H are positioned two cam rollers; As shown in Figure 6,the first of these, H, is in line with'the generally arcuate outer camslot H5. The second roller, H is in line with the more or lessirregularly curved inner cam slot or track H These cam members aremounted upon any suitable platform, positioned, as at H on the ede ofthe cradle, which platform tilts longitudinally with the members AMounted upon the to of the arm G are a plurality of sheaves I Of these,the sheave I is tangent to the central axis of the hollow shaft K andthe sheave I is closely adjacent the sheave I.

The shaft K is mounted for rotation about a vertical'axis, passingdownwardly through the platform H it being mounted in any suitablebearings K K It has mounted on its lower end the bevel gear K which isin mesh with the bevel pinion K upon the shaft K At the opposite end ofthe shaft K is a bevel gear K in mesh with the bevel pinion K on theshaft K K indicates any suitable gear reduction and K any suitable powersource, for example a motor. K is any suitable solenoid brake forcontrolling the ac tuation of the motor. 2

Mounted on the shaftK is the drum L.

Dead-ended on the drum L is the cable L which passes about a sheave Lfixed on the frame of the cradle, and about the sheave L fixed on theguides L along which moves the large weight L It will be understood thatthe guides L arev fixed to the cradle frame.

The cable continues about the sheave L and downwardly through the largeweight L terminating in a small weight L In the initial position ofthedevice, the weight L hangs somewhat below the bottom ofthe weight L asshown in Fig. 3. The weight L rests upon stops orangles L as shown inFigs. 3 and 5. The sheave L is suspended at one end of a second cable M,which cable passes about the fixed sheaves M M M M and M M beingtangential to the central axis of the shaft K. The cable end passesupwardly through the center of the hollow shaft K and thence about thesheaves I and I along the length of the arm G, and about the sheaves Gto be deadended finally upon the arm G as at M It will be realized thatwhereas I have described and shown a practical and operative device,nevertheless many changes might be made in size, shape, number,disposition and relation of parts without departing from the spirit ofmy invention. I therefore wish my drawings to be taken as in a broadsense illustrative and diagrammatic, rather than as limiting me to myprecise disclosure. The use and operation of my invention are asfollows:

My deflector is particularly adapted for use in unloading grain fromfreight box cars which are first tilted laterally, to free the in nercardoor from the door frame, and are then tilted longitudinally to causethe grain to flow out through the side door of the car. However, I donot wish to be limited to the use of my device with any particular typeof car, as it may be used with avariety of cars. Inthe use of such adevice the memberD is first advanced to position against the inner door,as shown in Figure 2. The car is then tilted laterally and the member'Dwith the door upon it takes the position in which they are shown in Fig.9. The motor A is then 7 actuated to tiltthecradle and the carlongitudinally. After the initial escape of the grain, and in order toclear from the car such grain as remains, for example such grain asgathers in' the cor ners of the car, I insert, at an angle across thefloor of the car, the deflector mem-' ber E. It is important that thismember be inserted angularly across the car, as shown for example inFig. 6. Assuming that the deflector is in initial position folded up asshown in Figs. 1 and 7. I actuate the motor K to rotate the shaft K, andthereby to move the arm G in a clockwise direction, considering theparts in the position in which they are 7 shown in Figs. 6 or 7. As thearinG rotates into the full line position'in which it is shown in Fig.6, the roller H first engages the cam' track H and'moves the shoe Hinwardly along the arm G. Shortly before the roller H escapes the trackH the secend roller H engages theouter cam track H? The effect of'thiscombined cam action is to move the shoe H inwardly along the arm G andto rotate the block G and with it the deflector member E, '.nto thefinal or operative osition in which theyare shown in fulliline in Fig.6. lVhen the parts are in the initial position in which they are shownin Fig. 7, the counterweight L is at the upward limit of its movement,with the smaller. weight L engaging the bottom of the weight'L, since itis through the weight L and the cable L that the larger weight is heldin its uppermost position. As the parts rotate to the final position,the cable L is paid out by the drum L and permits the weight If to dropto its lowest position against the stop L The large weight reaches thisposition at the time when the deflector is in the dotted line positionin Fig. 9. Referring to the lower right-hand corner of the deflector asshown in Fig. 9, the dotted line X indicates the path of this cornerafter the large weight ends its excursion. The lateral movement of theend of the arm G continues, the deflector being thrustfurther into thecar, but the deflector itself, and the arm G overcome the weight of thesmall weight L and therefore the deflector is able to sink downwardlyinto contact with the floor of the car, and to slide forwardly along thefloor of the car. until the final position is reached. When thereflector actually reaches the floor of the car and rests against it,the proportion of the parts is such that the weight L still. has alittle slack and can pull the cable L down sufliciently so that theweight hangs clear of and somewhat below the bottom of the large weightL This serves to keep the cable taut. When the movement of the deflectorhas been completed. and it is thrust as far into the car as isnecessary, the car is tilted longitudinally and the grain flows againstthe forward overhanging face of the deflector and flows outwardlythere-along to escape to the receiving bins. conveyors or the like.

It will be observed, as from Fig. 9, that by moving or tilting thedeflector downwardly before thrusting it to the limit of itsexcursioninto the car, the member D and the door I) are cleared by thedeflector, which passes easily beneath them. The overhanging portion Eof the deflector serves to check any tendency of the grain to flow overthe upper edge of the deflector.

After the tilting operation is completed, the deflector is removed byagain initiating rotation of the motor K The shaft K is rotated in areverse direction and, as the arm G begins its counter-clockwiserotation, the deflector E slides outwardly along the car floor until theweight L engages the bottom of the big weight. As it does so, the bigweight overcomes the resistance by gravity of the deflector itself andthe deflector tilts upwardly until the stop G engages the bottom of thearm G At this time the deflector has taken the dotted line position asshown in Fig. 9. When the stop G engages the bottom of the arm G the armhas rotated upwardly until it engages the upper stop G". Thistermination of the movement of the deflector E and the arm G in relationto the arm G causes the beginning of the upward movement of the weight Lwhich is accordingly reeled in by rotation of the drum L. Thereafter thedeflector E maintains a. constant relationship to the block G and theblock and deflector, as a unit, are folded or jack-knifed against thearm G through the action of the link H, until the device reaches itsinitial position. Meanwhile the cable L draws in on the weight L,raising it to its uppermost position.

As a matter of co venience in operation, I provide a stationary platformshown in Fig. 2 and generally indicated as 0. Upon it may be anysuitable electrical controlling means 0 whereby the various motors maybe actuated.

Among the characteristic features and advantages of my invention are thefollowing. The deflector may be compactly folded up along the side ofthe cradle and requires small side clearance for its operation wheninserted in the car. This permits the use of a wide, iuidisturbedoperators platform close to the side of the car. The deflector isinserted into and removed from the car, so far as the operator isconcerned, by a single movement of the handle of the controller ineither forward or reverse direction. Although the electrical controls donot of themselves form part of the present device, it will be understoodthat the operation is interlocked electrically, so that the deflectorcannot be inserted except when the cradle of the unloader is horizontal,or when the end to which the deflector is attached is raised above itsnormal position. Owing to the necessity of maintaining the parts in arestricted space, the employment of two cam tracks is advantageous, thesecond track, farther from the center of rotation of the deflector thanthe first, taking up the guiding operation at the extremity of thecamming movement in relation to the first track. Since the deflectorslides along the floor of the car at a time when the floor is inclinedto a position downwardly below the level of the control platform and thelevel of the plane of the car tracks when the car is in its initialhorizontal position, it is necessary to lift the deflector to clear thenormal top of the cradle. It is for this purpose that the cable systemsare used and the extent of the movement of the small weight before itcontacts the large counterweight determines the point at which thelifting of the deflector takes place.
